looking for some advice when profiling tight (sometimes close to a vertical wall) corners on patterns. these are made from a red urethane called tooling board. Its fairly hard stuff. the issue is that some of the corners have to be filleted pretty tight (up to 1/16 fillet) that mean getting into tight corners with a 1/8" ball endmill sometimes having to hang my tool out up to 3 inchs. I work in the pattern industry similar to mold making, however molds usually have enough draft along the walls to not have to worry about this. because of the tool length i need, any chatter i get while cutting rides up the side of the wall and looks horrible. ive attatched some pic showing what im talking about. because of the almost vertical walls i cannot use a tapered tool holder. Any advice or suggestions to this issue?
thanks
